The orders were also against three other men which it was claimed had formed the "Duleek Partnership" to acquire lands for development.

AIB sought the judgment orders arising from a number of loans it advanced between 2003 and 2009 in connection with the purchase of a site at Duleek, Co Meath.

Mr Justice Kelly granted summary judgment, finding none of the four had made an arguable defence to the bank's claim such as would allow the matter go to a full hearing.

Mr Mansfield Jnr appealed the decision. The other three did not appeal.

Mr Mansfield, a son of the late hotelier and property developer Jim Mansfield, argued the Commercial Court erred in its decision. It was claimed that he signed a document by mistake - Mr Mansfield said he is dyslexic, and cannot read properly. AIB opposed the appeal.

The Court of Appeal found Mr Justice Kelly was correct in his approach.

While it was accepted Mr Mansfield had certain difficulties regards reading, he was a businessman with commercial experience, the three-judge appeal court said.
